at an angle of incidence, either by mechanical power or by utilizingthe force of gravity.

. The object ofmy invention is to provide a means for controlling the aeroplane by maintaining or restoring. its equilibrium or lateral balance, both vertically and horizon- Y tally. In machines of the aeroplane type, the device is supported by reason of the impingement of the air upon the under surface of one or more planes, the impingement surface being presented at an angle 01"". incidence. The relative movements of the air and the aeroplane can be derived from the motion of the air in the form of wind blowing in adirection opposite'to that in which the device is going or by a combined downward and forward motion of the machine, as in starting from an elevated position. In either case the action is that of soaring Power being applied to the machine to drive it forward will cause the air to support it in a like manner. In all cases, owing, to the varyingconditions to be met with, there are.

numerous disturbing forces which tend to shift the machine from the position which it should occupy to obtain the desired results. By my invention this difficulty is remedied, and I am able to change. the posi-. tion of the machine at will, thereby restoring and maintaining equilibrium. Y

My invention consists in the novel c0ntrolling plane, its mounting and connections, as I shall now fully describe by reference to the accompanying drawings in which Figure 1 is a perspective view of one end of a biplane aeroplane showing the application of my invention, the controlling plane or curtain being in a rolled up position out of use. Fig. 2 is an end view of the same, the controlling plane or curtain being shown drawn from its roller at an upward angle. Fig. 3 is an end view, similar to Fig. 2, but with the controlling plane drawn at a downward angle. Fig. 4: is a front view of a biplane in full, showing the controlling planes 8 is an end View of the same.

plan view showing the application of my I at each end, one being. at an upward, angle and the otherat a downward angle, the positions being such'as to rightthe machine. Fig. 5 is an end view of a bi-plane showing the use of two controlling lanes at one end and reversely operating. Fig. 6 is a view showing a dilferent position of the roller of the controlling plane, but resultin in the presentation of the plane at ang e to the direction of travel of the machine. Fig. 7

is a view showing the application of my invention to one end of a mono-plane. Fig.

Fig. 9 1s a invention as a rudder-in a vertical plane. ;Fig. 10 is a view showing it as a rudder in a horizontal plane. i

In Fig. 1, are shown the sustaining planes 1 and 2, and the i1prights'3 of one end of a bi-plane aeroplane. Between two of the front uprights is mounted a roller 4. good way of mounting this roller is by journaling its ends in one of the wings 5 of a tubular bracket 6 secured on the upright. This roller 4 is a spring controlled one of any suitable kind. A good way to keep it under rotative tension is to attach an arm? to its journal end, the other end of the arm bein connected with a spring 8, which is fastened to a hook 9on the other wing 10 of the bracket 6. Mounted upon this roller 4 so that it may wind upon it and be unwound from it, is a flexible sheet or curtain 11, of suitable nature, fabric or other material, the free end of the curtain being hemmed and a stiffening bar 12 inserted. Mounted in the other wing 10 of the bracket 6' is a guide roller 13 which lies parallel with and separated from the curtain carrying roller 4, in such position as to direct the curtain 11, either up over said guide roller or down under it. Wire or other connections 1e extend from the free edge of the curtain upof the wires is pulled upon and the otherpaid out by a single movement. 'If it be desired to present the control-plane or curtain 1.1, at an upward angle as shown in Fig. 2!, the upper Wires 1-1 are pulled upon, so that the curtain is unwound from its roller, while the lower wires pay out and over the guide of functional surface, and it will be observed.

that on account of the wire connections and their directions and the tension of the roller l, these angles of presentation will be invariable. \Vhen the curtain is presented at an upward angle as in Fig. 2, the effect will be to lower that end of the machine. .Vhen presented at a downward angle, as in Fig. 3, its ellect is to raise said end. These curtaincontrols will, ol? course, be at each end of the machine. This I show in Fig. 4t, wherein the aeroplane is shown as tilted laterally and the curtains set relatively oppositely, that on the left or higher end of the figure being at the upward angle, and that at the right or lower end being at the downward angle, which positions are those required to right the machine. In this view are shown the wire connections 14: and 16, so arranged,

, and connected with a single operating lever 1,8, that when the lever is moved in one d1rection'ono ot the curtains will be presented at an upward angle and the other at a downward angle and vice veria. It is not essential, though 1 deem it the best arrangement, lllfihtlltf same curtain be presented at either angle. Thus in Fig. I show two separate curtains one below designated by 11. and one above by 11. These are operated by suit able connections ll), the lower one being arrangi'cthto be pre.--:cntcd at an upward angle and the upper one at a downward angle. Nor it essential that the curtain move from front to rear. It may be mounted as shown at ll" in Fig. (3, in which arrangement the curtain moves lengthwise of the device but at the required angle to the direction of travel ot the machine.

Although I have, thus l ar, described my invention as applied to bi-planes, it is evi. dent that it is equally applicable to mono- )ltlIiCH as I show in l i s. 7 and 8. In these r llgun-s 20 1S the sustaining plane of the dclhe curtain 11 is here mounted on the forward edge of one end of the plane, it being understood that another similar curtain is to be mounted on the other end oi the plane. The curtain is here adapted to be presented above the plane 20 at an upward angle and below it at a downward angle.

In Fig. 9, I show the eurtain-control 11 as applied for use with a vertical rudder 21 being here adapted to be presented at either side.

In Fig. 10 I show the curtain-control 11 as applied for use with a horizontal rudder 22.

Having thus described my invention what is claimed as new and desired to be protected by Letters Patent is-- 1. In an aeroplane, and in combination with the sustaining plane or planes of the device, a controlling plane adapted to be presented at a fixed angle either above or below the direction of travel of the device, and means for augmenting and diminishing the functional surface of saidcontrolling plane.

2. In an aeroplane, and in combination with the sustaining plane or planes of the device, a controlling plane adapted to be presented at a fixed angle either above or below the direction of travel of the device, and means for extending and contracting said controlling plane to augment or diminish its functionalsurface. v

In an aeroplane, and in combination with the sustaining plane or planes of the device, a controlling plane adapted to be presented at a fixed angle either above or below the direction of travel of the device, and means for fur-ling and unfurling said controlling plane to diminish or augment its functional surface.

4. In an aeroplane, and in combination with the sustaining plane or planes of the device, a. controlling plane adapted to be presented at a fixed angle either above or below the direction of travel of the device, and means "for rolling up and unrolling said controlling plane to diminish or augment its functional surface.

In an aeroplane, and in combination with the sustaining plane or planes of the device, a controlling means comprising a spring controlled roller, a llexihle sheet carried by said roller, connections to unwind the sheet from the roller in a plane at an angle on either side of the directi in of travel of the device, and a guide roller parallel ill) with and separated from the sheet-carrying roller to direct the unwinding oi the sheet iii-either angle.

In testimony whercoi' I have signed my name to this specification in the presence of 1 two subscribing witnesses.
